Well, I know they won a Grammy. Congrats to them. I am just not an Indie Rock kind of guy. Now, here is a group that won a Grammy too, but you would not know it for the did this pre-show. Best metal performance: Iron Maiden-El Dorado http://www.youtube.com/watch?v=coBzy-tPdws
Yay for Arcade Fire ... Canadian band! And since everyone's posting hard rocking videos ... here's The Ramones, first and greatest punk band, with a live cover of California Sun ... (stay for the overly-intense rock-out around the 1 minute mark) YouTube - Ramones - California Sun Live
Ramones kick arse. I saw them three times with other punk bands. I like "Beat on the Brat". YouTube - The Ramones - Beat on the Brat Abner
